Oh okay..thought i need to format my HDD using some sophisticated methods. I used partition fixer about 10 times and tried copy old versions of compatibility and newest. Still nothing. I have only AuroraCrash plugin in my dashlaunch but i cant turn it off. Dont think this is the problem...The hddx partition formatting should delete the old files by itself and install new ones, so no worries. If that's what you did, you're all set. MrMario2011's vid you posted in OP is still good to follow.
I dont even have Component input on my console. So i cant try 50/60Hz. Maybe the change of mainboard is the problem? I had Winchester and service changed it to Corona. Maybe someone can upload a version of game which is 100% compatible and works for you. I will check Really dont know what can i do to launch any Xbox Classic game on my 360. I can use only some adapters to component ? but i dont know if its the reason to do this.
